Answer:
The solutions are -0.65 and 4.65.
Step-by-step explanation:
3x^2 - 12x = 9
Divide both sides by 3
x^2 - 4x = 3
To make a square with "x^2 - 4x", you need to have a "+ 4" after it so it can be simplified as (x-2)^2. So add 4 to both sides.
x^2 - 4x + 4 = 7
(x-2)^2 = 7
x - 2 = (square root) of 7
x = 2 (+/-) (square root) of 7.
x = {-0.65, 4.65}
The solutions are -0.65 and 4.65.
hope this helps:)sorry if it doesnt

Answer:
P = 157.1 mm
Step-by-step explanation:
The perimeter of the figure = Circumference of circle + perimeter of square
We have, d = 11
⇒ Radius = 11 mm
Side of square = 22 cm
So,
So, the perimeter of the figure is equal to 157.1 mm.
Answer:
im pretty sure what u have ther is right
You can write the amount that they spent individually in a ratio where:
Holly : Jimmy
2 : 5
The total of this ratio would be 2+5 = $7.
To find the scale factor multiplier for the base ratio of 2:5:
35/7 = 5
Multiply both sides of the ratio by 5.
Holly : Jimmy
2 x5 : 5 x5
10 : 25
You can see that the total of this ratio is now $35, where Jimmy spent $25.
